I work with a charity that is aimed at helping disabled people access something they would not otherwise be able to. The charity recently paid for the able bodied volunteers to do disability awareness training with another charity.
In all honesty, I thought that the training was close to useless. We had a good laugh doing obstacle courses in wheelchairs and other such tasks, but I really don't think it taught me or any of the other volunteers anything that we weren't already aware of, not least because half an hour spend messing around in a wheelchair cant actually tell you what it is like to have to use a wheelchair permanently.
There are far too many disabilities with far too many variations that you could ever cover all of them on a days worth of expensive course.
I don't know what it's like to be disabled, I can try to understand issues that a disabled person may have to face, but I'm never going to fully get it unless it happens to me. The disabled people I work with have been consulted about how we could improve our service further and be more aware of their difficulties. The overwhelming response was that we just need to be willing to help where we can, be friendly and kind, but most importantly, just LISTEN to what they say they need help with and then respond to that.
There is nothing worse than someone doing disability training and then trying to tell a disabled person that they know what the person needs more than they do. (Hope that makes sense).
